WebWhat is FTIR? FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample. WebThe infrared spectrum reveals vibrations of atoms in molecules. The beauty of the spectrum is the close and accessible relationship between infrared bands and molecular structure. Certain groups of atoms have characteristic vibration frequencies which persist in different compounds. These groups (i.e. Si-OCH 3, C=O, Si-CH=CH 2, BF 4
